Note

Please contact the air conditioner manufacturer for testing and confirmation regarding system matching properties.
For air conditioners equipped with electronic expansion valves , please make sure to install a filter screen of 100 mesh or more in front of the valve.
When the air conditioner manufacturer assembles the welding pipe fitting , please make sure that the temperature of the valve body does not exceed 120°ºC.
If the product falls onto the ground accidentally or receives a violent impact , please stop using it . Return the product to our company for inspection before it can be used again .
Please inform us of the requirements of the electronic expansion valve and requirements of the coil when ordering goods.
The shape and value of the flow curve can be specified in accordance with the agreement between the two parties.
